onsemi NCL30188
The NCL30188 is a controller targeting isolated and non−isolated “smart−dimmable” constant−current LED drivers. Designed to 8 support flyback, buck−boost, and SEPIC topologies, its proprietary current−control algorithm provides near−unity power factor and 1 SOIC−8 NB tightly regulates a constant LED current from the primary side, thus CASE 751 eliminating the need for a secondary−side feedback circuitry or an optocoupler. The device is highly integrated with a minimum number of external components.| Part No. | NCL30188 |
